SMAD4 is part of the SMAD family of proteins that mediate signal transduction by the TGF-beta/activin/BMP-2/4 cytokine superfamily from receptor Ser/Thr protein kinases at the cell surface to the nucleus. SMAD4 promotes the binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides the function of activation required for SMAD1 or SMAD2 to stimulate transcription acts as a tumor suppressor. SMAD4 is a target molecule for functional inactivation in cervical cancer. SMAD4 is an important biomarker for malignant transformation atakes part in inducing apoptosis by modulating Bcl-2/Bax balance.

溶解建议
Sterile Filtered colorless solution. The SMAD4 protein solution contains 20mM Tris-HCl pH-8， and 20% glycerol.
保存建议
SMAD4 although stable 4℃ for 4 weeks， should be stored desiccated below -18℃.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
